Description

MACROCYCLIC HIV-1 PROTEASE INHIBITORS AND USES THEREOF

BACKGROUND OF THE INVENTION

[0001] HIV protease inhibitor-based active antiretroviral therapy (ART) has been proven to be most effective treatment regimens for HIV/AIDS. However, drug-side effects and emergence of drug-resistance are making ART far less effective or ineffective outright,

SUMMARY

[0002] The inventors have designed and developed a series of macrocyclic HIV-1 protease Inhibitors based upon X-ray structure of an inhibitor- bound HIV-1 protease. The macrocyclic inhibitors of the various embodiments described herein are capable of forming extensive hydrogen bonding interactions with the HIV-1 protease enzyme active-site backbone, an important concept behind the development of compounds against resisted HIV. While not wishing to be bound by any specific theory, it is believed that Inhibitors that contain a flexible macrocycie involving allow effective repacking at the mutation site. It is believed that this factor may influence the enzyme-inhibitory potency and antiviral potency of the compound of the various embodiments described herein. In addition, a number of the compounds of the various embodiments described herein have been shown to maintain potency against multi-drug- resistant HIV variants. This class of inhibitors may exhibit improved pharmacological properties compared to darunavlr and other FDA approved- Inhibitors.

[0013] Various examples of the present Invention also contemplate pharmaceutical compositions comprising one or more compounds of the various examples of the present invention (e.g., compounds of the formulae (I), (la), (lb), and (II)) and one or more pharmaceutically acceptable carriers, diluents, excipients or combinations thereof. A "pharmaceutical composition" refers to a chemical or biological composition suitable for administration to a subject (e.g., mammal). Such compositions may be specifically formuiated for administration via one or more of a number of routes, including but not limited to buccal, cutaneous, epicutaneous, epidural, infusion, inhalation , Intraarterial, intracardial, intracerebroventricular, intradermal, intramuscular, intranasal , intraocular, intraperitoneal, Intraspinal , Intrathecal, intravenous, oral, parenteral, pulmonary, recta!!y via an enema or suppository, subcutaneous, subdermal, sublingual, transdermal , and iransmucosa!. In addition, administration can by means of capsule, drops, foams, gel, gum, injection, liquid, patch, pill, porous pouch, powder, tablet, or other suitable means of administration.

[0014] A "pharmaceutical excipient" or a "pharmaceutically acceptable excipient" comprises a carrier, sometimes a liquid, in which an active therapeutic agent is formulated. The excipient generally does not provide any pharmacological activity to the formulation, though it may provide chemical and/or biological stability, and release characteristics. Examples of suitable formulations can be found, for example, in Remington, The Science And Practice of Pharmacy, 20th Edition, (Gennaro, A. R,, Chief Editor), Philadelphia College of Pharmacy and Science, 2000, which is incorporated by reference in its entirety.

[0021] Liquid dispersions for oral administration can be syrups, emulsions, solutions, or suspensions. The syrups can contain as a carrier, for example, saccharose or saccharose with glycerol and/or mannito! and/or sorbitol. The suspensions and the emulsions can contain a carrier, for example a natural gum, agar, sodium alginate, pectin, methy!cei!u!ose, carboxymethyiceiluiose, or polyvinyl alcohol.

[0022] The amount of active compound in a therapeutic composition according to various examples of the present invention may vary according to factors such as the disease state, age, gender, weight, patient history, risk factors, predisposition to disease, administration route, pre-existing treatment regime (e.g., possible Interactions with other medications), and weight of the individual . Dosage regimens may be adjusted to provide the optimum therapeutic response. For example, a single bolus may be administered, several divided doses may be administered over time, or the dose may be proportionally reduced or Increased as indicated by the exigencies of therapeutic situation.

[0023] "Dosage unit form," as used herein, refers to physically discrete units suited as unitary dosages for the mammalian subjects to be treated; each unit containing a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specification for the dosage unit forms of the Invention are dictated by and directly dependent on the unique characteristics of the active compound and the particular therapeutic effect to be achieved, and the limitations inherent in the art of compounding such an active compound for the treatment of sensitivity in individuals. In therapeutic use for treatment of conditions in mammals (e.g., humans) for which the compounds of the present Invention or an appropriate pharmaceutical composition thereof are effective, the compounds of the present invention may be administered in an effective amount. The dosages as suitable for this invention may be a composition, a pharmaceutical composition or any other compositions described herein.

[0024] For each of the recited examples, the dosage is typically administered once, twice, or thrice a day, although more frequent dosing Intervals are possible. The dosage may be administered every day, every 2 days, every 3 days, every 4 days, every 5 days, every 6 days, and/or every 7 days (once a week). In one example, the dosage may be administered daily for up to and including 30 days, preferably between 7-10 days. In another example, the dosage may be administered twice a day for 10 days. If the patient requires treatment for a chronic disease or condition, the dosage may be administered for as long as signs and/or symptoms persist. The patient may require "maintenance treatment" where the patient is receiving dosages every day for months, years, or the remainder of their lives. In addition , the composition of this invention may be to effect prophylaxis of recurring symptoms. For example, the dosage may be administered once or twice a day to prevent the onset of symptoms in patients at risk, especially for asymptomatic patients.

A heterocyciyi group designated as a C₂-heterocyciyi can be a 5-ring with two carbon atoms and three heteroatoms, a 8-ring with two carbon atoms and four heteroatoms and so forth. Likewise a C₄-heterocyclyl can be a 5-ring with one heteroatom, a 6-ring with two heteroatoms, and so forth. The number of carbon atoms plus the number of heteroatoms equals the total number of ring atoms. A heterocyciyi ring can also include one or more double bonds. A heteroaryl ring is an example of a heterocyciyi group. The phrase "heterocyciyi group" includes fused ring species including those that include fused aromatic and non-aromatic groups. Representative heterocyciyi groups include, but are not limited to piperldyny!, plperazinyl, morphoilny!, furany!, pyrrolldlnyl, pyridiny!, pyrazinyl, pyrimidinyl, trlazinyi, fhiophenyl, tetrahydrofuranyl, pyrro!yl, oxazoly!, Imidazo!yi, triazyoiy!, tetrazolyl, benzoxazoiiny! , and benzimidazo!lny! groups.

[0041] The term "aikoxy" as used herein refers to an oxygen atom connected to an alkyi group, including a cycioalkyi group, as are defined herein. Examples of linear aikoxy groups include but are not limited to methoxy, ethoxy, propoxy, butoxy, pentyloxy, hexyloxy, and the like. Examples of branched aikoxy include but are not limited to isopropoxy, sec-butoxy, tert-butoxy, Isopentyloxy, isohexyloxy, and the like. Examples of cyclic aikoxy include but are not limited to cyciopropyloxy, cyclobutyloxy, cyclopentyloxy, cyclohexyioxy, and the like. An aikoxy group can include one to about 12-20 or about 12-40 carbon atoms bonded to the oxygen atom, and can further include double or triple bonds, and can also include heteroatoms. For example, an allylox group Is an aikoxy group within the meaning herein. A methoxyethoxy group is also an aikoxy group within the meaning herein, as is a methylenedioxy group in a context where two adjacent atoms of a structure are substituted therewith.

[0042] The term "amine" as used herein refers to primary, secondary, and tertiary amines having, e.g., the formula N(group)₃ wherein each group can Independently be H or non-H, such as alkyi, aryl, and the like. Amines include but are not limited to a!kylamlnes, arylamines, ary!a!kylamines; dia!ky!amines, diarylamines, diaralkylamines, heterocyclyl amines and the !ike; and ammonium ions.

[0044] As used herein, the term "salts" and "pharmaceutically acceptable salts" refer to derivatives of the disclosed compounds wherein the parent compound Is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic groups such as amines; and alkali or organic salts of acidic groups such as carboxylic acids. Pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, and nitric; and the salts prepared from organic acids such as acetic, propionic, succinic, g!ycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, su!fanllic, 2-acetoxybenzoic, fumaric, toluenesulfonic, methanesu!fonic, ethane disu!fonic, oxalic, and isethionic, and the like.

[0045] Pharmaceutically acceptable salts can be synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods, in some instances, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, nonaqueous media like ether, ethyl acetate, ethanoi, Isopropanol, or acetonitrlle are preferred. Lists of suitable salts are found in Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., 1985, the disclosure of which is hereby incorporated by reference. [QQ46] The term "solvate" means a compound, or a salt thereof, that further Includes a stoichiometric or non-stoichiometric amount of solvent bound by non-covalent intermolecular forces. Where the solvent Is water, the solvate is a hydrate.

[QQ47] The term "prodrug" means a derivative of a compound that can hydroiyze, oxidize, or otherwise react under biological conditions (In vitro or in vivo) to provide an active compound, particularly a compound of the invention. Examples of prodrugs include, but are not limited to, derivatives and metabolites of a compound of the invention that include biohydrolyzabie moieties such as biohydrolyzabie amides, biohydrolyzabie esters, biohydroiyzabie carbamates, biohydrolyzabie carbonates, biohydrolyzabie ureides, and biohydrolyzabie phosphate analogues. Specific prodrugs of compounds with carboxyl functional groups are the lower alky! esters of the carboxylic acid. The carboxylate esters are conveniently formed by esterlfying any of the carboxylic acid moieties present on the molecule. Prodrugs can typically be prepared using well-known methods, such as those described by Burger's Medicinal Chemistry and Drug Discovery 6th ed. (Donald J. Abraham ed., 2001 , Wiley) and Design and Application of Prodrugs (H. Bundgaard ed., 1 985, Harwood Academic Publishers GmbH).
